The productivity of a pesticide residue laboratory is limited by the chromatographic run time. In a typical multi-residue LC-MS/MS method the run time is a compromise between the number of analytes, acceptable number of coelutions, the desired chromatographic peak width, and the minimum dwell time of the MS detector to achieve acceptable data quality. A very fast chromatographic run producing very narrow peaks can have a negative impact on sensitivity, selectivity and data quality. An effective solution is the use of a novel dual channel UHPLC system with two independent flow paths capable of operating two analytical columns simultaneously. Sample extracts are injected alternately on the two columns to either, increase sample throughput or reduce co-elution of compounds to improve data quality without increasing the time required for analysis while maximizing utilization of the mass spectrometer.
